' ROLLING-MILL TABLE.

Specification of Letters Patent.

Patented Feb. 1, 1921.

Application filed October 16, 1919. Serial No. 331,072.

T 0 all whom it may concern:

Be it known that I, LEWIS R. JAMEs, a

resident of Edgewater, in the county of Bergen and State of New Jersey, have invented a new and useful Improvement in Rolling-Mill Tables, of which the following is a specification.

This invention relates to lifting tables for rolling mills.

The objects of the invention com rise the provision of a table adapted to receive small billets of metal from a set of rolls and move them vertically into position to be passed into a second set of rolls. A further object is to provide such a table constructed so that the operator thereof may be carried thereon in relatively fixed position to the lifting table so that during the lifting process he can manipulate the billet, as by turning it by hand to proper positlon for reinsertion in the second pair of rolls.

The drawing shows diagrammatically in vertical section a two pass rolling mill with the lifting table in two positions, with the operator thereon.

Tables to move ingots from one level to another in order to pass them from one set of rolls into a second set at a different elevation are not new. But it is believed that such tables so constructed mounted and operated as to permit the operator thereof to remain in fixed relative position with respect to the ingot carried by the table, are new, and that is the function of the present r invention.

Referring to the drawing, upon a base 1 is mounted a suitable roll frame 2, carrying a primary set of rolls 3, and a secondary set 4, at a higher elevation than the first set. These rolls are suitably mounted in the housing member 5, as will be readily understood by those skilled in the art. Such details are not described herein, because well understood, and not a part of the present invention. To the left of the rolls 3, a feed table 6 is provided with ordinary rollers 7 thereon, to permit a billet to be easily passed into this set of rolls. This set of rolls is rotated as indicated by the arrow at its left.

After passing therethrough the billet 8 moves by ravity down the inclined chute 9, having Idle rollers 10 therein, and comes to rest upon the lifting table 11 composed of a supporting frame carr in idle rollers 12 and fixed supports 13, as? wi ll be readily understood from the drawings.

The frame 11 is mounted on a truss member 14 which extends from under the table horizontally to the right, supporting a platform 15 upon which an operator 16 may stand. The beam 14 is carried by a support mg frame composed of uprights 17 and cross brace members 18, as indicated in the drawmg. ThlS is mounted upon and fixed to a vertical plunger 19, which extends into a plston and is adapted to be hydraulicall operated in the ordinary manner of suc hoisting devices.

After the billet has come to rest on the rollers 12- of the lifting table it may be read ly manipulated by the operator by turning it end for end, or otherwise manually ad uStmg its position, as for example, by aid of a bar 20, as illustrated.

The operatlon of the apparatus is as follows: I

Billets are introduced into the rolls 3 from the supporting table 6, and after passage therethrough move by gravity onto the liftingtable 11, when the latter is in its lower position. As soon as the billet has been received thereon the operator sets in motion "in dotted lines, thus bringing the billets to the proper level to be fed into the upper pair of rolls 4. While the table is in motion, the operator, standin on the platform 15, which is a part 0 the rigid construction of the entire lifting apparatus, manlpulates the billet, so that when the table has reached its upper position the billet is in proper relation to the second set of rolls to be passed thereinto. Thereafter the table is dropped again to receive another billet, and so on. By this apparatus permitting an operator to be continually in the same relative position with respect to the billet which he has to move, his work is very greatly facilitated and expedited.

The mill is particularly adaptable for rolling very small billets or those of light weight, as for example, aluminum.

I claim:

1. A lifting table for rolling mills comprising asupport for the billet, another support attached to the first and forming a platform for the table operator.

lifting table adapted to support an operator, 10 and means to raise and lower the combined table and operator support.

In testimony whereof, I have hereunto set my hand.

LEWIS R. JAMES.
